When a new user tries to access a web site, the client will transparently re-direct them to the auth server where they can either log-in or sign-up. The client and the auth server then negotiate what to do with the client and either allow or deny them certain network access. 35 35 … … 38 38 Refer to the Wifidog Flow Diagram document for some more details. 39 39 40 Q: What does it run on ? 40 == Q: What does it run on ? == 41 41 A: The client runs on any Linux machine that has a working netfilter+iptables installation.

However our auth server at the time of this writing is not as polished as the client. Feel free to make it better or write your own from scratch. If you go with the later option you'll have to respect the same protocol the client uses for the whole system to work correctly. 50 50 51 Q: What does it look like ? 51 == Q: What does it look like ? == 52 52 A: The client is a daemon process that runs in the background.
